SharpPlot.DrawBubbleChart Method

Make an incidence plot from x and y data and marker scales.

Example

sp.SetMargins(6,18,24,4);
sp.SetMarkers(Marker.Bullet);
ydata = new int[] {190,270,310,120,190,230};
xdata = new int[] {17,31,29,14,16,24};
count = new int[] {12,65,77,7,9,112};
sp.BubbleChartStyle = BubbleChartStyles.ExplodeAxes|BubbleChartStyles.GridLines;
sp.DrawBubbleChart(ydata,xdata,count);

The short tutorial shows a few of the possibilities and some sample code.

Overloads

• public void DrawBubbleChart(int[] yValues,int[] xValues,int[] markerArea);
• public void DrawBubbleChart(int[] yValues,int[] xValues,double[] markerArea);
• public void DrawBubbleChart(double[] yValues,double[] xValues,int[] markerArea);
• public void DrawBubbleChart(double[] yValues,double[] xValues,double[] markerArea);

Description

This chart is a variant of the standard ScatterPlot with the size of the markers used to show an extra dimension in the data. The third argument gives the required marker area (typically the number of incidents recorded at a certain location) and all the markers are automatically scaled to cover the range of areas given.

Any marker may be used here (including user-defined markers) but simple solid circles are probably best. See the tutorial for some more possibilities.
